Lamp and Design Breakdown

The T5 HO (High Output) format delivers more light per inch than standard T8 lamps, making it an efficient choice for aquarium lighting where intensity and color accuracy matter.

The 22-inch length suits mid-size aquarium setups and is compatible with Zoo Med's T5 HO hood systems.
